Rapidly growing Frontline Technologies of Exton is moving into the 300,000-square-foot Endo Pharmaceuticals building in Malvern.

Frontline says by leasing 60,000 square feet this year and an additional 30,000 square feet in 2017, the firm will nearly double its working space.

Frontline is known far beyond Chester County by the hundreds of thousands of education workers who daily use its Aesop substitute placement and absence management system.  Aesop is used by more than 4,000 school districts. Frontline also offers VeriTime, a time and attendance management system, and Jobulator, a job notification tool for substitute teachers using Aesop.

Designed by L2 Partridge of Philadelphia and built by IMC Construction of Malvern, the five-story, two-building Endo complex is situated directly off the Pennsylvania turnpike at Atwater Corporate Center. It has views of Quarry Lake, a full-service cafeteria, conference rooms, a fitness center, a one-story parking deck and other amenities.

Endo continues to occupy 210,000 square feet of the 300,000-square-foot facility.

“The relocation of our headquarters into the Endo building illustrates just how quickly we are growing,” said Michael Blackstone, Frontline co-founder and managing partner. “This move will support the current momentum we are experiencing as a result of the expansion of our K-12 product line and rapid adoption of our products in the K-12 market.”

Since 1998 Frontline Technologies has focused on human capital management software for the K-12 education industry. More than 5,000 school districts and 2 million educators across the U.S. and Canada currently use its products.
